| 摘 要： | 以拖曳阵列与本舰所构成的声纳系统为例 ,从双平台观点考虑 ,利用对目标的两方位及时延的量测为依据 ,研究了该系统的目标运动分析 (targetmotionanalysis,TMA)问题。采用了最大似然估计、扩展Kalman滤波(EKF)方法 ,实现了对目标运动参数的估计 ,并给出了它们的Cramer Rao低界 (CRLB)。通过仿真考察了参数变化对估计精度的影响。仿真结果表明上述方法具有较高定位精度。该方法适合于主、被动形式的多平台系统 ,且容易实现。

| Abstract: | The problem of the TMA based upon hull mount arrays and ship is discussed in this paper in accordance with the measurements of bearings and time delay from two platforms. The MLE and EKF methods are used to make the parameter estimation and finally CRLB is given. Simulation shows that the parameter estimation error curves have a good convergence, and the locating ellipse reduces rapidly over time. The method is easy to realize in practice. |
